Re: [Haskell-cafe] Package Management with Stack?

Thanks for the suggestion, Adam. That does it for xmonad-contrib. Unfortunately, it fails when I go on to add xmonad-extras, probably because the version of xmonad already installed can't be resolved with the available version(s) of xmonad-extras. (I forgot to note exactly which packages I had before, so I'm installing these things one by one, based on compilation errors of ~/.xmonad/xmonad.hs.) $ stack install xmonad-extras hint-0.6.0 libmpd-0.9.0.6 --resolver lts-8.4 Error: While constructing the build plan, the following exceptions were encountered: In the dependencies for xmonad-extras-0.12.1: hint-0.6.0 must match >=0.3.3.3 && <0.5 (latest applicable is 0.4.3) libmpd-0.9.0.6 must match >=0.8 && <0.9 (latest applicable is 0.8.0.5) xmonad-0.13 must match >=0.10 && <0.13 (latest applicable is 0.12) xmonad-contrib must match >=0.10 && <0.13, but the stack configuration has no specified version (latest applicable is 0.12) Recommended action: try adding the following to your extra-deps in /home/jun/.stack/global-project/stack.yaml: - xmonad-contrib-0.12 You may also want to try the 'stack solver' command Plan construction failed. Adding the fact that I seem to have to list a lot of deps on the command line or in stack.yaml and Brandon's suggestion that I'm using this tool for the wrong purpose, this seems like a deal breaker for me :( On Sat, Mar 11, 2017 at 4:11 AM, Adam Bergmark wrote:

I use the global stack environment to install most executables, it works best when the package is in a snapshot of course. There is no need to change the global config, try this: stack install xmonad-contrib X11-xft-0.3.1 --resolver lts-8.4

You can also look for a stack.yaml in the repo of the executable and use that resolver + any extra deps on the command line, that'll most likely work even if the package isn't in a snapshot.

HTH, Adam

Stack does have a notion of a global project, which it uses if you're not in a project directory. The error message you received:

Error: While constructing the build plan, the following exceptions were encountered:

In the dependencies for xmonad-contrib-0.13: X11-xft must match >=0.2, but the stack configuration has no specified version (latest applicable is 0.3.1)

Recommended action: try adding the following to your extra-deps in /home/jun/.stack/global-project/stack.yaml: - X11-xft-0.3.1

tells you how to make X11-xft-0.3.1 available to the global project, which should allow you to install xmonad-contrib into this global package.

Am I fundamentally misunderstanding how stack is supposed to be used?

Stack is not a package manager. It is a reproducible builds tool. Ad hoc usage like you are doing is outside of its purview.

Also, last I checked, for some reason xmonad-contrib wasn't in stackage, so stack's primary mechanism for avoiding conflicts fails.
